Water quality - Guidance standard on monitoring freshwater pearl mussel (Margaritifera margaritifera) populations and their environment
This European Standard provides guidance on methods for monitoring freshwater pearl mussel populations and the environmental characteristics important for maintaining populations in favourable condition. The standard is based on best practice developed and used by Margaritifera experts in Europe, and describes approaches that individual countries have adopted for survey, data analysis and condition assessment. While it is recommended that the causes for pearl mussel decline should be urgently investigated, standard methods for restoring populations are beyond the scope of this document.
Wasserbeschaffenheit - Anleitung für das Monitoring von Populationen der Flussperlmuschel (Margaritifera Margaritifera) und ihrer Umwelt
Diese Norm enthält Anleitungen zu Verfahren für das Monitoring von Populationen der Flussperlmuschel und der Umgebungsbedingungen, die für die Erhaltung von Populationen im günstigen Zustand wichtig sind. Die Norm beruht auf der von Experten für Margaritifera in Europa entwickelten und angewendeten bewährten Vorgehensweise und beschreibt Herangehensweisen, die einzelne Länder zur Erhebung, Datenauswertung und Zustandsbeurteilung festgelegt haben. Obwohl empfohlen wird, die Ursachen für den Rückgang der Perlmuschel dringend zu untersuchen, fallen genormte Verfahren zur Wiederherstellung von Populationen nicht in den Anwendungsbereich dieses Dokuments.
Qualité de l'eau - Norme guide sur le suivi des populations de moules perlières d'eau douce (Margaritifera margaritifera) et de leur environnement
La présente norme fournit des préconisations concernant les méthodes de suivi des populations de moules perlières d'eau douce et présente les caractéristiques environnementales importantes pour le maintien des populations dans des conditions favorables. La présente norme est basée sur les meilleures pratiques développées et utilisées par les experts de la Margaritifera en Europe, et décrit les approches que les différents pays ont adoptées pour le recensement, l'analyse des données et l'évaluation de la situation. Même s'il est recommandé de rechercher de toute urgence les causes du déclin de la moule perlière, les méthodes standardisées visant à restaurer les populations dépassent la portée du présent document.
Kakovost vode - Navodilo za spremljanje (monitoring) populacij sladkovodnih školjk potočnih bisernic (Margaritifera margaritifera) in njihovega okolja
Ta standard podaja navodilo za metode spremljanja populacije sladkovodnih školjk potočnih bisernic in okoljske značilnosti, ki so pomembne za vzdrževanje populacije v ugodnih pogojih. Standard temelji na najboljši praksi, ki so jo razvili in jo uporabljajo evropski strokovnjaki za bisernice, ter opisuje pristope, ki jih posamezne države uporabljajo za pregled, analizo podatkov in oceno pogojev. Med tem ko je priporočljivo, da naj bi se vzroke za znižanje populacije potočnih bisernic nujno raziskalo, ta dokument ne zajema standardnih metod za obnovo populacije.
